DAVENPORT-BED.

' Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed September 4.1906. Serial No. 333.075.

To all whom, it may concern:

Be it known that I, CHARLES A. JONES, a citizen of the United States ofAmerica, residing in the city of St. Louis, in the State of Missouri,haveinvented certainnew and useful Improvements inDavenport-Beds, ofwhich the following is a full7 clear, and exact description, referencebeing hadto the accompanyingdrawings, forming part of thisspecification.

My invention relates to an improvement in t-hat class of `folding bedscommonly termed davenport-beds7 and which are convertible into acondition for useas a bed or as a seat.

The present invention has for its object to provide means whereby themovable section of the bed is automatically rotated upon an aXis intransferring said movable section from the position it occupies when thepiece of furniture is being used as a seat to the position it occupieswhen the piece of furniture is being used as a bed, and vice versa.

Figure I is an end elevation of my davenport-bed with portions brokenaway for the purpose of affording a view of the partsv back of them.Fig. II is a view of one end of the bed partly in rear elevation andpartly in section.

In the drawings I have illustrated only one end of the bed, and it is tobe understood that the construction of the parts illustrated at this endand to be described are duplicated at the opposite end of the bed.

A designates the stationary section of my bed, which is supported ateach end by leg members B, preferably of inverted-U shape.

O is the movable section of the bed, which is adapted to rest in anupright position upon the stationary section to provide a back when thepiece of furniture is to be used as a seat and is also adapted to bemoved into a position in horizontal alinement with and in front of thestationary section when the piece of furniture is to be used as a bed.

1 designates a link which serves lto connect the movable section O tothe stationary section A, the said link being preferably of flanged formand having applied thereto a face-plate 2, whereby the linkis renderedof boX-like construction, in order that it will accommodate certainmechanical parts to be hereinafter described.

3 (see Fig. II) is a stud attached to the stahereinafter more fullyappear.

tionary section A at its end and to which the lower end of the link 1 isloosely fitted ain order that said link may turn thereon. The stud 3terminates in a stem 4, to which is rigidly secured a sprocket-wheel 5.

6 is a stud projecting from the end of the movable section C and towhich the link l .is loosely fitted for the purpose of roviding movementof said stud in said linli, as will The stud 6 has fixed to it aspur-wheel 7, that occupies a position at the outer side of the link 1.

8 designates a shaft that is journaled in the link 1 and its face plate2. This shaft serves as a support for a s ur-Wheel 9, that meshes withthe spur-whee 7 and has rigidly associated with it a sprocket-wheel 10.

11 designates a chain that operatesupon the sprocket-wheel 5, and 12 isa chain that operates upon the sprocket-wheel 10. These chainsareconnected by rods 13 and 14, one of which-for instance, that 14 hasintroduced thereinto a turnbuckle 15, whereby the sections of chain maybe drawn more tightly to the sprocket-wheels on which they operate orwhereby the chains may be loosened, as may be required. The chains 1land 12 and the'rods connecting them constitute in reality a beltthatoperates upon the sprocket-wheels 5 and 10, and while I havedescribed the chains as consisting of sections united by rods I wish itunderstood that I do not desire to be limited to the particular form ofbelt herein set forth. The connecting-link 1 terminates at its lower endin an arm l', that is united by a spring 16 to the forward leg of theleg member B.

In the practical use of my davenport-bed the operation is as follows:Assuming the parts to be in the position illustrated in full lines inthe drawings, in which the piece of furniture is illustrated incondition for use as a seat, the operator toVmove the movable section Cinto horizontal alinement with the stal tionary section A, so that thepiece of furniture may beused for a bed, grasps the movable section andswings it forwardly. As the movable section is moved it carries the link1 to an upright position.. During this movement of the parts the chain11, fitted to the sprocket-wheel 5, is operated in a manner to impartmovement to the chain 12, fitted to `the sprocketwheel 10, and as aresult the spur-wheel 9 is rotated and motion is trans- ICO mitted fromsaid spur-wheel to the spur- Wheel 7, that is fixed to the movablebed-section C. As a conse uence, said movable section C is swung in t earc of a circle, so that when the link 1 reaches the upright position(indicated'by dot-and-dash lines, Fig. I) the movable section C willoccupy the horizontal inverted position. (Also indicated by dotand-dashlines.) The forward movement of the parts is continued, and the link 1and the movable section C move into the positions indicated by heavydotted lines, Fig. l, the movable section being at this time again in avertical position, but located at the forward side of the stationarysection A and being reversed from its former position. The movement ofthe parts is continued until the movable bed-section is placed inhorizontal alinement with the stationary bed-section, right side 11p, itbeing understood that throughout the entire period a continuous rotationof the movable bed-section is carried on through the medium of themechanism described.

y17 designates a leg that is located at the inner side of and carried bythe movable bedsection and is adapted to support said section when it isin horizontal alinement with the stationary bed-section. It is to beunderstood that when the piece of furniture is to be again convertedinto a seat the parts move reversely from the movement that has beendescribed to turn them to their former positions. When the piece offurniture is being converted to a bed from a seat, the movable section Cis readily transferred to a position in alinement with the stationarysection A, and while it is being transferred the spring 16 is expanded.When the movable section is being again transferred to convert the pieceof furniture into a seat, said spring acts upon the link 1 to assist inelevating the movable section and returning it to a raised `positionabove the stationary bed-section.

18 designates a shiftable head or foot section that is adapted to bemoved forwardly l to the end of the movable .bed-section when saidsection is in alinement with the stationary section andthe piece offurniture is to be used as a bed. This head or foot member is providedwith a slotted upright 19, that receives a stud 20, carried by the link1 or its face-plate?, preferably the latter. The member 18 is positionedin guides 21, carried by the leg member B, and is adapted to slidewithin said guides. As the movable bed-section is transferred to convertthe piece lof furniture into a bed the head or foot member is slidforwardly, due to the operation of the pin 20 in the slotted upright 19of said member, andwhen the movable bed-section is again returned to itsposition above the stationary bed-section the head or foot member isretracted into the position illustrated in full lines, Fig. I.
